Hi Jeroen, i have downloaded the oct 4/2017 version of https://our.umbraco.org/projects/developer-tools/1-1-multilingual-example/. The project works well, but implementing it in my own project to get different urls per node in two languages: English and spanish i'am getting the following error in the GetOtherUrls method. specifically in this code:

for (int i = 0; i < domains.Count; i++)
{
             // Get the domain and matching parent url.
              var otherDomain = domains[i];
              var otherParentUrl = parentUrls[i];
             // Get the parent url and add the url segment of this culture.
             var urlSegment = content.GetUrlSegment(otherDomain.LanguageIsoCode);
                                    urls.Add(otherParentUrl.EnsureEndsWith("/") + urlSegment);
  }

in the line : var otherParentUrl = parentUrls[i];

this is the exception:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource) at System.Collections.Generic.List1.get_Item(Int32 index) at Umbraco.Extensions.UrlProviders.MultilingualUrlProvider.<>c__DisplayClass1_0.<GetOtherUrls>b__0() in C:\Projects\NET\PolancoPlastica\PolancoPlasticaWebPage\PolancoPlastica\Umbraco.Extensions\UrlProviders\MultilingualUrlProvider.cs:line 144 at Umbraco.Core.Cache.CacheProviderExtensions.<>c__DisplayClass5_01.

any help would be very appreciated,
